Used extensively by forensic professionals, this chemical reacts catalytically with the hemoglobin in blood. The resulting vivid purple coloration allows investigators to extract critical ridge detail from porous and non-porous surfaces. Experts rely on this targeted reagent to reveal intelligence that might otherwise remain completely invisible.\u003c\/p\u003e\n\u003cp\u003eEngineered for demanding crime laboratory workflows, the dry powder provides mixing flexibility to maximize print visibility. By formulating custom solvent and catalyst ratios, examiners achieve court-admissible visual enhancements even on previously cleaned or heavily absorbed stains. When incorporated into specific processing sequences, the chemical wash reveals the finest minutiae for high-resolution photographic documentation. This bulk format significantly reduces overall laboratory reagent costs.\u003c\/p\u003e\n\u003cp\u003eTo prevent sample degradation, investigators must carefully document the evidence immediately once the desired contrast is achieved. Maintaining proper handling ensures the delicate print structures remain intact while the background clears. For optimal laboratory safety, preparation and mixing of this fine particulate should always occur within a certified fume hood. Technicians must utilize appropriate personal protective equipment to prevent inhalation or contact.\u003c\/p\u003e\n\n\u003ch2\u003eAvailable Sizes and Configurations\u003c\/h2\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;border:1px solid #ddd;margin:1em 0\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n  \u003cth style=\"border:1px solid #ddd;padding:8px 12px;background:#f5f5f5;text-align:left;font-weight:600\"\u003eSKU\u003c\/th\u003e\n  \u003cth style=\"border:1px solid #ddd;padding:8px 12px;background:#f5f5f5;text-align:left;font-weight:600\"\u003eVolume\u003c\/th\u003e\n  \u003cth style=\"border:1px solid #ddd;padding:8px 12px;background:#f5f5f5;text-align:left;font-weight:600\"\u003eFormat\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n  \u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003ePF15024-25g\u003c\/td\u003e\n  \u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003e25 g\u003c\/td\u003e\n  \u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003ePowder\/Bottle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;border:1px solid #ddd;margin:1em 0\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n  \u003cth style=\"border:1px solid #ddd;padding:8px 12px;background:#f5f5f5;text-align:left;font-weight:600\"\u003eSpecification\u003c\/th\u003e\n  \u003cth style=\"border:1px solid #ddd;padding:8px 12px;background:#f5f5f5;text-align:left;font-weight:600\"\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eProduct Type\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003ePresumptive Blood Reagent Powder\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eTarget Material\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eHemoglobin (Latent bloodstains)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eDeveloped Color\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eVivid Purple \/ Violet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eApplication Phase\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eLatent blood enhancement (after mixing)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003ePreparation Requirement\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eMust be mixed with solvent and catalyst\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eLaboratory Applications\u003c\/h2\u003e\n\u003cp\u003eFor specialized forensic environments, integrating this unique developer is critical when processing violent crime scenes. Crime scene investigators frequently encounter evidence where perpetrators have attempted to clean away biological material or where blood has soaked deeply into porous substrates like carpets, untreated wood, and clothing. Because it selectively reacts with trace hemoglobin, the formulated solution is highly effective at rescuing difficult prints. Extracting usable intelligence requires a chemical approach designed specifically for these microscopic deposits.\u003c\/p\u003e\n\u003cp\u003eWhen processing evidence, the laboratory-prepared working solution is typically applied using a fine mist spray method over the suspected area. Technicians gently coat the surface and monitor for the immediate color change reaction that indicates the presence of blood. Upon achieving optimal ridge definition or pattern transfer, the evidence is immediately photographed under standard lighting conditions. This critical documentation step ensures maximum resolution before the background begins to over-develop.\u003c\/p\u003e\n\n\u003ch2\u003eForensic Reagent Comparison: Why Choose Rocky Mountain Reagents?\u003c\/h2\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;border:1px solid #ddd;margin:1em 0\"\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth style=\"border:1px solid #ddd;padding:8px 12px;background:#f5f5f5;text-align:left;font-weight:600\"\u003eFeature\u003c\/th\u003e\n      \u003cth style=\"border:1px solid #ddd;padding:8px 12px;background:#f5f5f5;text-align:left;font-weight:600\"\u003eRocky Mountain Reagents LCV Powder\u003c\/th\u003e\n      \u003cth style=\"border:1px solid #ddd;padding:8px 12px;background:#f5f5f5;text-align:left;font-weight:600\"\u003eTypical Competitor\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eQuality Control\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eHigh purity \/ strict traceability\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eUnverified purity\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eFormat\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eDry powder for custom mixing\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003ePre-mixed only (shorter shelf life)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003ePricing\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eBelow retail pricing\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eFull retail\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eShips From\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eUSA inventory\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:8px 12px\"\u003eVaries\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eAcademic and Institutional Pricing\u003c\/h2\u003e\n\u003cp\u003eLabSupplies.com offers tiered quantity pricing for academic and research institutions.
